Based on what I've read, I think my LT/AT is right around 180 bpm. Maybe a bit lower, like 178, but pretty close. That said, when I climb my local big (ish) mountain (Mt. Diablo), my average HR is 184 over the 77-minute climb. Does it sound reasonable that I would be able to ride at about 2 or 3% OVER my LT/AT for 77 minutes in the middle of a 4+ hour ride?
I should also note that my max HR is 200 bpm on the bike and 210 bpm running. Using the 210 bpm figure, my 180 LT/AT figure is about 86% of my max HR.
Am I missing any big pieces here?
